Where are my postgres *.conf files, dude?

Question

Recently reinstalled postgre 8.3 on my Ubuntu 8.04 after update. Used EnterpriseDB package. I can connect to the database locally, I see system DB postgres but I can't configure it because I can't find config files. Searched through entire hard drive and found only samples like pg_hba.conf.sample

Where they are?

Answer 1

Run

sudo updatedb

followed by

locate postgresql.conf

Answer 2

Or ask your database:

SHOW config_file;
